Streamlight's SolarStream is a supplemental solar charging panel for emergency responder vehicles. It helps to offset battery drain from computer systems and other rechargeable electronics when a vehicle is off, extending battery life. A thin-film amorphous silicon charging panel, the Streamlight SolarStream adheres to a variety of contoured surfaces. It maintains a trickle charge to the vehicle battery even in low sun and cloudy conditions, and is both heat and shade tolerant. The Streamlight SolarStream comes with a 5-year limited warranty and has an MSRP of $400.
The VOXX Power System (POWV3.5) is an installed battery-backup system that ensures your cruiser, SWAT van, CSI truck, and many more emergency vehicles start after sitting with their lights on, computer booted up, or other accessories running at the scene.
